A wheelchair (10), preferably with three wheels (18, 24), with a front wheel support (12.1) embodied as a transverse support. The front wheel support (12.1), together with two inclined supports (12.2), which adjoin its ends and are orient ed backward and upward, forms a U-like integral support, which is connected with an axle tube (14) of the rear wheels (18). A wheelchair (10) with a seat (52), whic h has adjustably inclined lateral longitudinal seat supports (56). The longitudina l seat supports (56) are connected with longitudinal supports (12.3), which are inclined rearward and downward, of the frame of the wheelchair (10) indirectly b y their front ends, and connected by their rear ends via seat struts (72) with adjustable effective strut length with said longitudinal supports (12.3). A wheelchair with an adjustable inclination of the rear wheel axles, wherein the r ear wheel axles, which are embodied as full floating axles, are received in end area s of a rear axle tube (14), namely in angle adapter sleeves (22). These angle adapter sleeves comprise a section with a bore (22.2, 122.2) for receiving the f ull floating axles and an area (22.3, 122.3) with a detent surface, which extends obliquely in respect to the axes of these bores (22.2, 122.2). The angle adapter sleeves (22) are received in a longitudinally adjustable manner in the end areas of the axle tube (14.1, 14). A fixation device (22.7, 22.8) is provided in order to fix each angle adapter sleeve (22) selectively in place in one of several positions. A seat module (50) for a wheelchair (10), comprising a seat (52), which can be fastened on the frame (12.3) of the wheelchair (10), and a backrest (54), which is fastened on the seat (52), but cannot be fastened to the frame (12.3) of the wheelchair (10), and use of the seat module (50) in connection with a wheelchair (10). Use of a wheelchair (10) with a bike, wherein the wheel base of the wheelchair (10) is changed to prevent it from tilting backward in that the rear wheels (18) are moved from their customary position into a position which is further toward the rear. |
